The Miami Dolphins play in the AFC East and have been there for years and years. This is not news to them or anyone else. And so it stands to reason they should know that the teams they have to match up against, first and foremost, are their AFC East rivals.
They play those rivals six times every single season.
And if they cannot beat those rivals, they cannot matter in the postseason scheme of things.
This season the Dolphins have not won even one game against Buffalo, New England or the New York Jets. They are 0-4 against those teams with Sunday's rematch at New York up next.
